This is an Android app that can detect Bluetooth signals emitted from Corona vaccinators, distinguishing them from normal signals emitted from smartphones, earphones, etc. This was created by Mr. Zaurus with the help of engineer Mr. Joe Nagoya.
No special machinery is required, it simply runs as an Android app; no iPhone version has been created; it is supposed to be available for all Android 8.0 (2017) and later, and even earlier with OS updates.
There is no iPhone version. It works with most current Android. Even old Android may be usable if updated to 8.0 or higher.
